Description

This application claims the priority of Taiwanese patent application number 102210657 , filed on 6 June 2013.

BACKGROUND OF THE INVENTION

1. Field of the invention:

The present invention relates to a paper product manufacturing technology, and more particularly to a paper cutting mechanism comprising a cutting unit controllable to move a circular cutting edge into a cutting recess for cutting paper material conveyed by a material conveying stand and an anvil unit controllable is to move anvil wheels in contact with the paper material during a cutting operation of the circular cutting edge or to move away from the paper material after each cutting operation of the circular cutting edge.

2. Description of the Related Art:

The use of wooden casings, boxes and paper boxes for the storage and packaging of commercial products is widespread. However, wood boxes are usually heavy and expensive, and not suitable for delivery. Furthermore, nails are usually used for packing wooden boxes. Cartons and paper boxes have the advantage of being lightweight and low in cost. Furthermore, cartons and paper boxes may be packaged with an adhesive, a hot melt adhesive or tape to facilitate packaging. Packaging a product in a carton or paper box can effectively protect the product against shock damage and simplify the delivery or storage of the product. Therefore, the use of cartons and paper boxes for packaging low weight products is widespread.

• 1. Wenn das Schneidrad C abgesenkt wird um das Papierflächenmaterial B zu schneiden, wird es auch in die Borsten D1 der Rundbürste D schneiden, wodurch die Borsten D1 beschädigt oder abgeschnitten werden und wodurch die Betriebslebensdauer der Rundbürste D verkürzt wird.
• 2. Wenn das Papierflächenmaterial B geschnitten wird, wird das Schneidrad C abgesenkt, allerdings bleibt die Position der Rundbürste D unverändert. Da der Abstand zwischen der Rundbürste D und dem Schneidrad C in der unteren Begrenzungsposition und der erhobenen Position der Rundbürste D nicht einstellbar sind, werden die Borsten D1 im Bereich um die Rundbürste D herum regelmäßig von der Scheidkante C1 um den Schneidkörper C2 des Schneidrads C herum geschnitten, wodurch die Rundbürste D schnell abnutzt.

Furthermore, the production of corrugated paper or board requires a number of process steps, including splicing, preheating, molding, gluing, cooling, lamination with an outer layer, fitting, cutting, stacking, etc. Furthermore, during the manufacture of cartons or paper boxes corrugated or cardboard-like surface materials to be tailored to the desired sizes. 4 illustrates a paper cutting mechanism for this purpose from the prior art. As shown, the paper cutting mechanism comprises a conveying unit A for conveying paper sheet material B between a vertically movable cutter wheel C and a round brush D, allowing the paper sheet material B to be supported by the bristles D1 of the round brush D and the cutting edge C1 around the cutting body C2 of the cutting wheel C to be cut around. According to the function of the round brush D to support the moving paper sheet material B, the cutting wheel C can accurately cut off the paper sheet material B, however, this prior art configuration of the paper cutting mechanism still has disadvantages, as summarized below.

• 1. When the cutting wheel C is lowered to cut the paper sheet material B, it will also cut into the bristles D1 of the round brush D, thereby damaging or cutting off the bristles D1 and shortening the service life of the round brush D.
• 2. When the paper sheet material B is cut, the cutting wheel C is lowered, but the position of the round brush D remains unchanged. Since the distance between the circular brush D and the cutting wheel C in the lower limit position and the raised position of the circular brush D are not adjustable, the bristles D1 in the area around the circular brush D regularly around the cutting edge of the cutting wheel C about the cutting body C2 C2 cut, causing the round brush D wears off quickly.

Therefore, it is desired to provide a paper material cutting mechanism which avoids the disadvantages of the aforementioned prior art and which has a long service life.

SUMMARY OF THE INVENTION

The present invention has been made against the background of these circumstances. It is therefore a principal object of the present invention to provide a paper material cutting mechanism which allows relative movement between the cutting unit and the anvil unit, preventing the cutting edge from cutting directly into the anvil wheels of the anvil unit and reducing the risk of anvil wheel damage.

To achieve these and other objects of the present invention, a paper material cutting mechanism of the present invention comprises a cutting unit and an anvil unit. The cutting unit comprises a material conveyor frame for conveying paper material for cutting and defining a cutting recess therein, a cutter holder fixed below the material conveyor frame, a cutter rotatably mounted on the cutter holder, and a driver central with the cutter Blade holder is connected and which is controllable to move the blade holder up and down between a cutting position, in which the cutting edge is inserted into the cutting recess, and a non-cutting position, in which the circular blade is kept away from the Schneideaussparung. The anvil unit is disposed above the cutter holder of the cutting unit, comprising a rotatable bracket, a plurality of anvil wheels centrally secured to the bracket, and a driver configured to move the rotatable bracket up and down to transport the anvil wheels between an operative one Position in the vicinity of the material conveyor frame around the cutting recess and a non-operational position spaced from the material conveyor frame.

Furthermore, the driver of the cutting unit may be a pneumatic cylinder or a hydraulic cylinder, which is designed for the up and down movement of the cutter holder. Furthermore, the cutting edge of the cutting unit is a circular cutting edge. When the circular blade is inserted into the cutting recess, it cuts off the moving paper material.

Furthermore, the driver of the anvil unit may be a pneumatic cylinder or a hydraulic cylinder. Furthermore, the anvil wheels are selected from the group consisting of round brushes, soft plastic wheels, rubber wheels and silicone rubber wheels. By moving the anvil wheels toward the cutting unit to the operative position, the anvil wheels support the moving paper material to be cut by the circular cutting edge of the cutting unit. Since the anvil wheels and the circular blade are movable relative to each other, the cutting depth of the circular blade is controlled relative to the anvil wheels, thereby preventing anvil wheel damage and extending the service life of the anvil wheels.
